slice: Slice DRIFT-spectrum by wavenumbers

In omega1x/spectrotest: Manipulate with DRIFT-spectroscopy data

Description

Return a subset of a DRIFT-spectrum in the given range of wavenumbers.

Usage

slice(x, k, left, right)

Arguments

x	an object of S3-class drift.
k	a wavenumber, [1/cm]. If given only one channel is extracted from DRIFT-spectrum and further arguments are ignored.
left	a wavenumber, [1/cm]. If given indicates the lowest wavenumber in wavenumber range.
right	a wavenumber, [1/cm]. If given indicates the highest wavenumber in wavenumber range.

Value

An object of S3-class drift.

Examples

 s <- coal_drift()

 # extract one channel at 2000 1/cm:
 s1 <- slice(s, 2000)
 plot(s1)

 # make slice starting from 2000 1/cm:
 s2k <- slice(s, , 2000)
 plot(s2k)

 # make slice up to 1000 1/cm:
 s1k <- slice(s, , , 1000)
 plot(s1k)

 # subset in CO2 region:
 s2 <- slice(s, , 2399.44, 2411.02)
 plot(s2)
